Chris Brown loses his temper at charity basketball game

Los Angeles - Chris Brown was spoken to by police after an argument at a charity basketball game.

The Beautiful People singer became visibly upset at the Power 106 Celebrity Basketball Game at USC on Sunday and reportedly got into a heated exchange with a spectator in the stands, though loud music made it difficult to hear the nature of their row.

One of the officers at the event at USC's Galen Centre in Los Angeles could be heard saying in footage of the incident: "I don't care who's here, get it straight."

The 27-year-old singer also sparked controversy when he refused to stand for the National Anthem before the game.

Singer Tank had urged the crowd to stand in respect for the victims of the 9/11 terror attacks 15 years ago, but Chris remained seated and appeared to share a laugh with his friends as those around them got to their feet.

However, he stood at the end and applauded the R&B star's vocals.

Following news that Chris Brown had lashed out at a fan, Power 106 tweeted that "there was a security issue but it had nothing to do with a fan" which Chris Brown then shared on Instagram.
